Market. Who bought the product has the right for free buy a package of two products.

[Vladimir Karputov]

For example: there are two product-# 1 and # 2. Both paid. After buying the product #1 you must be able to boot (no extra charge) a package of product # 1 + # 2 product.
Such packages can be timing for different holidays or events or no reason.

[Ovidiu Caslariu]

Need it want it make it happen!
